Cannot changing password in Forefront TMG SP1, new password does not meet the minimum complexity requirements

Question

I
have a problem. I publish SharePoint web site in Forefront TMG server (HTML Form Authentication, Windows (Active Directory) Authentication Validation Method). I can successfully login to web site, but I can`t change password. I
mark “I want to change my password after logging on”.
When I try change password to new, I have error message “Either the
user name or old password is not valid, or the new password does not meet the minimum complexity requirements. Please try again.” Password is fully corresponds with minimum complexity requirements.

In
DC I have Warning message:

Log
Name:System

Source:Schannel

Event
ID:36886

Description:

No
suitable default server credential exists on this system. This will prevent server applications that expect to make use of the system default credentials from accepting SSL connections. An example of such an application is the directory server. Applications
that manage their own credentials, such as the internet information server, are not affected by this.

Only difficulty consisted in deliveries of certificate on Windows 2008 R2 server. It was to issue a certificate for Windows XP Workstation
and after export it on a 2008 server.

Thank you!
